[GLORYSWORD]

Hi everyone 

I just bought galaxy A15

Without charger as you know,

 I'm using 15w charger now cause I don't have 25w and I don't want to use a copy charger & and is very expensive 

?My question:Is that effective on the battery

Hi @GLORYSWORD 

I'd only recommend to use a known brand of charger. 

The phone will draw what power it needs. 

You'll be fine using a good brand 15w charger.

@GLORYSWORD: The Galaxy A15 supports up to 25W charging via a compatible Samsung USB-C and plug adapter, so you're fine to use a 15W adapter without any detrimental effects on your battery.

Same here, but with S21 and S24 (Exynos). Tried with original Samsung 25w charger and a 30W from other brand. Also tried with a 100w certified cable, and with the original cable.

Charging is limited to 15W on both phones on every charger.

Self-update (for everyone in my same condition): I'm now trying with a more modern charger (EP-T2510N instead of EP-TA800N), maybe recent phones need a more recent charger.

Exist LOT of quick charge protocols: phone and charger (and sometimes cables too) have to "speak" the same language to negotiate a power raise
